??? 直聯旋片抽水環負壓泵是在旋片式抽水環負壓泵的根本上路經框架、村料和開發新工藝上重要機構改革后的的一種新泵種。 ??? Mono-block Rotary-vane Vacuum Pump is a kind of new pump, which is designed on the basis of rotary-vane vacuum pump through major reforms of structures, materials and manufacturing process. ???直聯泵有密度小、產品質量輕、振動式小、風噪低等顯著特點，選代替按照在高精密實驗儀器系統上使用的。 ??? Mono-block pump has the features such as small size, light weight, small vibration and low noise etc. It is suitable for the installation in the use of precision instrument and equipment. ???直聯泵選用三相四線或單相電交流溝通電機馬達直聯驅動程序。 ??? Mono-block pump is directly driven by three-phase or single-phase AC motor. ??? 可簡單采用，以成做種類真空環境裝置的前級泵。 ??? It can be used alone, and also can be used as prepump for various vacuum system. ??? 直聯泵附有氣鎮保護裝置，可能抽取具有刺激性一段次數的 可凝性有機廢氣氣體。 ??? Accompanied by gas-ballast equipment, mono-block pump could extract a quantity of condensable gas. ???直聯泵不要應運于騰出塵埃什么意思及的腐蝕影響、易爆性汽體，不恰充當降低泵或輸料泵利用。 ??? Mono-block pump can not be used as compression pump or delivery pump to extract dusts, corrosive and explosive gas.

??特點/Features:

???含量更小，含量更輕 ???吵音更低，運動更小 ???停泵防返油，開啟以便于 ???快卸蝶閥法蘭通道對接，并帶嘴
